The lasting legacy of the "rocket girls" of JPL

California-based Jet Propulsion Laboratory (JPL) has been central to the US missile and rocket development and operations for decades, and from the beginning that technology's success rested on a corps of expert mathematicians, people known as computers. And from the beginning they were all women, in a time when such opportunities were few and far between. You can find pictures of them, but names have not been well-recorded ... until now. Nathalia Holt found many of those women and wrote about their experiences in her book, Rise of the Rocket Girls: The Women Who Propelled Us, from Missiles to the Moon to Mars. [more inside]

Zubbles, the Colorful Bubbles

Finally, finally - Zubbles are available for pre-order! Inventor Tim Kehoe has been searching for the elusive colored bubble for a long time. Through his experimentation he's stained his eyes a deep blue, along with his car, his kitchen, and his bathtub (he's also permanently stained the family dog). But in 2005, after 11 years and over $500,000 in funding, Kehoe successfully created a colored bubble that wouldn't stain. His invention, Zubbles, was given the "Best of What's New, Grand Award" from Popular Science. [more inside]

Summer's coming. Time for invisible dye.

Sunscreen's a pain, but sunburn is worse. UV-protective clothing is expensive and not to everyone's taste. Instead, treat your own cotton, rayon, or silk clothing to make it sun-protective. Some clothing is inherently protective, but you can easily burn right through a new shirt, especially if it gets wet. A couple of boxes of either of two different brands of a wash-in UVA/UVB blocker will invisibly increase the SPF of a whole washer-load of clothing from 5 to 30 (repeat for an SPF of 50). The stuff wears off after a season's worth of launderings, so use a permanent marker to note the year of treatment inside the collars.

Live and let dye?!

Live and let dye?! Hair dyeing causes non-Hodgkin's lymphoma, especially in cases of repetitive dyeing over years, especially with darker colors.

This might sound trivial, until the names of some potential victims are mentioned. Jacqueline Kennedy Onasis, Joey Ramone, Louis Malle, Charles Lindbergh, King Hussein of Jordan, Paul Tsongas, Gabriel Garcia Marquez, William Casey, Roger Maris, Mickey Mantle, Steve Reeves, and Mr. T. (Shaddup, foo! I'm in remission!) Not that any of them would ever dye their hair, of course.
